ACTIVE TRANSPORT Flashcards
FANCY DEFINITION OF ACTIVE TRANSPORT
ACTIVE TRANSPORT IS THE MOVEMENT OF PARTICLES AGAINST A CONCENTRATION GRADIENT, USING ENERGY RELEASED DURING RESPIRATION
ACTIVE TRANSPORT, LIKE DIFFUSION AND OSMOSIS IS USED TO (…)
MOVE SUBSTANCES IN AND OUT OF CELLS
EXAMPLE OF ACTIVE TRANSPORT
IN THE DIGESTIVE SYSTEM WHEN THERE IS A LOW CONCENTRATION OF NUTRIENTS IN THE GUT, BUT A HIGH CONCENTRATION OF NUTRIENTS IN THE BLOOD
HOW IS ACTIVE TRANSPORT ALSO USED IN PLANTS
ITS HOW TTHEY GET MINERALS FROM THE SOIL (LOWER CONCENTRATION) INTO THEIR ROOT HAIR CELLS (HIGHER MINERAL CONCENTRATION)
WHEN THERES A HIGHER CONCENTRATION OF NUTRIENTS IN THE GUT…
THEY DIFFUSE NATURALLY INTO THE BLOOD
WHEN THERE IS A LOWER CONCENTRATION OF NUTRIENTS INN THE GUT THAN THERE IS THE BLOOD…
THE CONCENTRATION GRADIENT IS THE WRONG WAY
ACTIVE TRANSPORT ALLOWS NUTRIENTS TO BE TAKEN INTO THE BLOOD, DESPITE THE FACT THAT…
THE CONCENTRATION GRADIENT IS THE WRONG WAY
ACTIVE TRANSPORT NEEDS (…) FROM (…) TO MAKE IT WORK
ENERGY FROM RESPIRATION
WHAT ARE THE FOUR FACTORS THAT AFFECT THE MOVEMENT OF SUBSTANCES
1) SURFACE AREA
2) DISTRANCE
3) TEMPERATURE
4) CONCENTRATION GRADIENT
WHY DOES SURFACE AREA AFFECT THE MOVEMENT OF SUBSTANCES
THE RATE OF DIFFUSION, OSMOSIS AND ACTIVE TRANSPORT IS HIGHER IN CELLS WITH A LARGER SURFACE AREA TO VOLIUME RATIO, THIS MEANS THE SMALLER CELL HAS A LARFGER SURFACE AREA TO VOLUME RATIO
THE SMALLER THE CELL, THE LARGER THE SURFACE ARE TO VOLUME RATIO, SO, SUBSTANCES WOULD MOVE IN AND OUT OF THE CELL FASTER
WHY DOES DISTANCE AFFECT THE MOVEMENT OF SUBSTANCES
IFSUBSTANCES HAVE A SHORT DISTANCE TO MOVE, THEY WILL MOVE IN AND OUT FASTER
WHY DOES TEMPERATURE AFFECT THE MOVEMENT OF SUBSTANCES
AS PARTICLES IN SUBSTANCES GET WARMER THEY HAVE MORE ENERGY- SO THEY MOVE FASTER
WHY DOES CONCENTRATION GRADIENT AFFECT THE MOVEMENT OF SUBSTANCES
SUBSTANCES MOVE IN AND OUT OF A CELL IF THERES A BIG DIFFERENCE IN CONCENTRATION BETWEEN THRE INSIDE AND THE OUTSIDE OF THE CELL- SO IT INCRREASES THE RATE OF DIFFUSION AND OSMOSIS BUT NOT ACTIVE TRANSPORT
